When it comes to bookshelf speakers in 2024, two compelling options stand out: the newly released JBL Stage2 250B ($399) and the established KEF Q350 ($699). Let's explore how these speakers compare and help you decide which might be right for your setup.
Bookshelf speakers, despite their name, are actually designed to sit on stands or shelves at ear level. They serve as the sweet spot between larger floor-standing speakers and smaller desktop models. These versatile speakers can anchor a serious music system or serve as front channels in a home theater setup.
The key aspects that matter most are:
The JBL Stage2 250B and KEF Q350 take fundamentally different approaches to creating high-quality sound. JBL uses a traditional two-way design, where separate drivers handle high and low frequencies. The tweeter (which handles high frequencies) uses JBL's latest High-Definition Imaging (HDI) waveguide technology, which helps control how sound spreads into your room.
KEF, on the other hand, uses their signature Uni-Q driver array, where the tweeter sits in the center of the midrange/bass driver. Think of it like a speaker within a speaker. This design aims to create what audio engineers call a "point source" - where all frequencies appear to come from the same spot, just like they would from a live instrument.
The JBL Stage2 250B presents a more dynamic, forward sound that really brings movies and energetic music to life. When watching action scenes or listening to rock music, you'll notice the speakers' ability to handle sudden loud sounds (transients) with ease. The new HDI waveguide technology helps create a wide "sweet spot," meaning you don't have to sit exactly centered to get good sound.
The KEF Q350's Uni-Q driver creates an incredibly coherent sound where everything seems to blend naturally. Voices and instruments sound remarkably true to life, with excellent spatial positioning - you can easily tell where each sound is coming from in the recording. The bass extends slightly deeper than the JBLs, though both benefit from a subwoofer for home theater use.
For pure music listening, the KEF Q350 edges ahead with its refined presentation and exceptional imaging (the ability to place instruments and voices in space). The Uni-Q driver really shines with acoustic music, jazz, and classical recordings where accuracy is paramount.
The JBL Stage2 250B, while not quite as refined, delivers an engaging and dynamic performance that many listeners might actually prefer. It has a slightly forward midrange that makes vocals really stand out, and its efficient design means it can play quite loud with modest amplification.
In home theater applications, both speakers excel but for different reasons. The JBL Stage2 250B really shines here, handling movie soundtracks with authority and delivering dialog with excellent clarity. The HDI waveguide helps spread sound evenly across your viewing area, making every seat a good one.
The KEF Q350 creates an incredibly precise soundstage that can make movies feel more immersive, though it might not hit quite as hard during explosive scenes. Its more neutral presentation works well across all content types.
Released in early 2024, the JBL Stage2 250B represents the latest in JBL's speaker technology at a remarkably accessible price point. At $399 per pair, they deliver performance that competes with speakers costing significantly more.
The KEF Q350, while more expensive at $699, justifies its premium price through superior build quality and refined sound. The Uni-Q technology is constantly being refined, and while this model isn't brand new, it remains highly competitive in its price class.
Both speakers are well-built and should last many years. The JBL's more conventional design might be easier to repair if something goes wrong down the line. The KEF's more complex Uni-Q driver could be more expensive to replace, but the overall build quality is notably superior.
The JBL Stage2 250B is slightly more forgiving of room placement and works well in small to medium-sized rooms. They can be positioned closer to walls thanks to their front-firing port design.
The KEF Q350 benefits more from careful placement and room treatment but rewards the effort with exceptional imaging and soundstage. They need a bit more space from walls due to their rear port design.
The JBL speakers are easier to drive, working well with most modern receivers rated at 20-150 watts per channel. The KEFs are slightly more demanding and benefit from quality amplification, though they're still compatible with most modern receivers.

Both speakers represent excellent choices for different users. The JBL Stage2 250B offers remarkable value and performance, especially for home theater use. The KEF Q350 delivers a more refined experience that will satisfy critical music listeners.
Remember that speaker choice is somewhat personal - if possible, try to listen to both before making a decision. Many dealers offer home trials, which can be invaluable in making the right choice for your specific situation.
In terms of value, the JBL Stage2 250B is hard to beat, offering about 80% of the KEF's performance at 57% of the price. However, if budget allows and music is your primary focus, the additional investment in the KEF Q350 will reward you with superior refinement and long-term satisfaction.

The JBL Stage2 250B ($399) is generally better for home theater use, offering more dynamic sound and better dialog clarity. Its HDI waveguide technology creates excellent sound dispersion across multiple viewing positions. While the KEF Q350 ($699) is also capable, it's more optimized for music listening.
For critical music listening, yes. The KEF Q350 offers superior imaging and more refined sound. However, for home theater or casual listening, the JBL Stage2 250B provides excellent value at nearly half the price.
Both are relatively efficient, but the JBL Stage2 250B is slightly easier to drive with its 6-ohm impedance. The KEF Q350 works well with most modern receivers but benefits more from higher quality amplification.
For home theater use, yes. While both speakers offer good bass for their size, a subwoofer is recommended for either the JBL Stage2 250B or KEF Q350 to achieve full-range home theater performance.
The JBL Stage2 250B is more forgiving in small rooms due to its front-firing port design. The KEF Q350 needs more space from walls due to its rear port design.
Both can be wall-mounted, but it's not ideal for optimal performance. The JBL Stage2 250B includes keyhole brackets, while the KEF Q350 requires separate mounting hardware.
The KEF Q350 has superior build quality with heavier materials and more refined finishing. The JBL Stage2 250B offers good build quality for its price point but isn't quite as premium.
The JBL Stage2 250B integrates better with other JBL speakers and offers excellent performance for surround sound. The KEF Q350 works well too but is typically overkill for surround channels.
The JBL Stage2 250B features newer technology, being released in 2024. However, the KEF Q350 uses a proven design that remains competitive and highly regarded.
Both speakers perform best on proper speaker stands at ear level. The JBL Stage2 250B works well with 24-26 inch stands, while the KEF Q350 needs 22-24 inch stands due to its larger size.
The KEF Q350 excels with music streaming, offering more detailed and refined sound. The JBL Stage2 250B performs well but doesn't reveal quite as much detail in complex music.
While both can be used as computer speakers, it's overkill. The JBL Stage2 250B is more practical for this use due to its lower price point, but both speakers are really designed for room listening rather than near-field desktop use.
